The present invention is a double-stage gas injecting charger, that is, a container supplied on a container mounting table by two or more concentrically arranged inner and outer container mounting rows and corresponding rows of gas injecting charger ports. The present invention relates to a charger that is operated as a charger mechanism for injecting a pressurized gas, generally an inert gas, into a container filled with the pressurized gas in advance, and filling a liquid such as a chemical liquid. In the conventional gas injection charger as a prior art, first, a pressurized gas, such as a pressurized non-combinable gas, is filled into a container while the opening of the container is sealed as a bottle opening packing of a filling nozzle, and the filling liquid is pressurized in this container. The pressure in the vessel is released to the outside by opening the snift hole of a small flow area and gradually releasing the pressurized gas in the vessel to the outside before separating the opening of the vessel from the bottle opening packing. The bottle opening is separated from the opening of the container.

By the way, in the double-charger which doubled this gas-filled charger, even if a container was supplied only to one of each pair of filling nozzles inside and outside, even if there is no bottle, the inside and outside filling is prevented. An apparatus for opening and closing the valves of the nozzles independently is provided.

By the way, in the conventional apparatus, each valve opening / closing control mechanism is separately installed so as to operate independently. For example, since each valve opening / closing mechanism is provided at a low position in the outer valve and a high position in the inner valve, the valve operation mechanism becomes complicated. In addition, since the sniffer mechanism attached to the valve opening / closing mechanism is provided separately for the internal and external charger mechanisms as well as the valve opening / closing mechanism, the complexity of the sniffer mechanism is also inevitable due to the complexity of the valve opening / closing mechanism. There was a drawback that the entire apparatus became large and expensive.

In addition, since the gas injector is to fill the filling liquid in a container filled with pressurized gas, the risk of the bottle being broken is so great that it is not comparable to the charger used for the unfilled gas. In order to eliminate the damage completely, there is a great demand for measures. However, in the conventional apparatus, the bottle is damaged because the distance between the pair of container mounting bases and the filling nozzles for mounting and lifting the container is fixed mechanically. The danger was inherent.

In other words, since a pair of vessel mounting tables are usually moved up and down at the same time, it is not necessary to operate both mounting tables independently. Therefore, in principle, it is possible to make a pair of lifting devices in common. When a pair of container holders is provided in one lifting device, the distance between each pair of container holders and the corresponding filling nozzle is determined mechanically, so that mixing of containers having different dimensions or Due to the difference in distance between the containers, excessive force is applied to only one of the containers squeezed between the pair of container placing table and the filling nozzle, which may cause the container to break.

Thus, the scattering of the filling liquid and pressurized gas due to the breakage of the bottle loses the effect of not being filled without the bottle, and thus preventing the breakage of the bottle is as important as the effect of not being filled without the bottle.

Accordingly, an object of the present invention is to provide a multi-gas injection charger including a pair of filling mechanisms, which are highly componentized, have fewer components, and have a simplified structure.

In addition, another object of the present invention is to provide a simple valve operation mechanism for a pair of internal and external filling mechanism to prevent the valve from opening even when there is no container in the container mounting table to achieve the effect of not being filled without the bottle.

Another object of the present invention is to ensure that the breakage of the container is not easily generated, and therefore, to ensure that the bottle is not filled without the above-mentioned bottle, and that the filling liquid and this pressurized gas are not scattered to the surroundings in any case, To provide a charger.

Another object of the present invention is to simplify the structure of the sniff mechanism by associating a sniff mechanism for extracting pressurized gas from a container after filling with a pair of charger mechanisms.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The double-gas injection charger shown in FIG. 1 supplies empty containers to supply vessels (A) and (B) via the supply side Star Wheels 101 and 102, and returns the containers.

A fork-shaped arm 9 which cooperates with the valve 8 of the filling nozzle is formed, and the cam 10 is fixed to the outer end of the rotating shaft 7.

Accordingly, the valves 5 and 8 of the filling nozzles inside and outside the filling nozzles are rotated through the respective arms 4 and 9 by rotating the rotary shafts 3 and 7 through the cams 6 and 10, respectively. Each can be opened and closed independently. Next, a detection operation mechanism for detecting the presence or absence of a container and separately opening and closing the above-described valves 5 and 8 will be described.

Each of the casings 2 above is provided with elevating sections 11a and 11b, respectively, before and after each rotational direction of the normal portions 2c and 2c in the vertical direction. The well-known bottle opening guide members 12a and 12b are mounted over the lower end of the elevating section 11a and 11b, respectively, and the rollers 13a and 13b are attached, respectively.

On the other hand, the bracket 14 provided in the fixing frame of the charger is supported by a hollow shaft 15b in which a shaft 15a is rotatably held, and an arm 16a at one end of each shaft 15a, 15b. 16b is fixed.

Each arm 16a, 16b is a container guide mechanism 17a (17b) comprised of the bottleneck guide members 12a, 12b, the lifting leg 11a, 11b, and the rollers 13a, 13b, respectively. Is located at the lower end, it does not interfere with the guide mechanisms 17a and 17b, but when each guide mechanism 17a and 17b is raised to the ascending end by the containers 18a and 18b, respectively, 16a is comprised so that the roller 13a may rotate the arm 16b in the direction of the arrow a of FIG. 3, respectively, interfering with the roller 13b.

Arms 19a and 19b are fixed to the other ends of the shafts 15a and 15b, respectively, and one end of the connecting rods 20a and 20b is connected to the ends of the arms 19a and 19b. have.

The other ends of the connecting rods 20a and 20b are connected to the ends of the interference compensators 22a and 22b, respectively, attached to the shaft 21 attached to the fixing frame of the charger.

The interference arm 22a is provided at the position where the cam 6 of the valve opening / closing mechanism mentioned above and the interference arm 22b are mutually interfered with the cam 10 of the same mechanism, and the arm 16a (as described above) ( When the shafts 16b are rotated in the direction of the third degree arrow a by the rollers 13a and 13b, respectively, the shafts 15a and 15b, the arms 19a and 19b and the connecting rods 20a and 20b are respectively rotated. Each interference compensator 22a, 22b is rotated in the direction of FIG. 3 arrow b, respectively, and the interference compensator 22a, 22b does not interfere with the cams 6 and 10. It is possible to move from the position to the interfering position. 5 and 6 show the sniffer mechanism attached to the valve opening / closing control mechanism, and the valve block 24 is disposed and fixed between the lower ends of the normal portions 2c and 2d in the vertical direction. have.

The valve blocks 24 are provided with passages 25a and 25b for filling nozzles inside and outside, and gas nozzles 26a and 26b constituting filling nozzles are inserted into the passages 25a and 25b, respectively. .

As is well known in the art, the filling liquid valves 5 (8) (FIG. 4) of the filling nozzle are provided above the respective passages 25a and 25b, and the openings of the vessels 18a and 18b are valve blocks. It is compressed by being sealed to the bottom face of (24) or the bottleneck packing provided in the bottleneck guide members (12a) and (12b) below the valve block (24).

Therefore, after the filling liquid is filled in the vessels 18a and 18b and the filling liquid valve is closed, pressurized gas is introduced into the remaining space in the upper portion of the vessels 18a and 18b and the passages 25a and 25b. .

The sniffer mechanism for gradually escaping the enclosed pressurized gas into the air includes a pair of sniffer valves 27a and 27b for opening and closing the shunt holes, and a snift shaft 28 for simultaneously operating each sniffer valve. It consists of the cam 29 which operates this shunt shaft 28. As shown in FIG.

The sniffer hole includes orifice passages 30a and 30b opened in the respective passages 25a and 25b, spring receiving chambers 31a and 31b extending to the orifice passages, and the valve block It is comprised from the radial direction hole 33a, 33b of the normal member 32 fixed to 24, and the axial hole 34 of the said normal member 32, and mentioned above sniffer valve 27a ( 27b protrudes into each of the holes 34 by the springs 35a and 35b in the spring storage chambers 31a and 31b, which are regrettable in the holes 33a and 33b. In that state, the end valve part of each sniffer valve 27a (27b) is settled in the valve seat of the periphery of the hole 33a, 33b, and the sniffer hole is closed.

The cam 29 is formed in a linear shape, the top of which is pinched by the pin 36 to the valve block 24, and a cam surface 29a is formed on the rear surface thereof.

On the other hand, the sniffer bamboo 28 is slid freely in the above-mentioned axial hole 34, and the tip is elastically contacted with the cam surface 29a of the cam 29 mentioned above by the spring 37. As shown in FIG.

A pair of cam portions 28a and 28d are formed at a predetermined position of the axial shaft 28, and the cam portions 28a and 28b are respectively engaged with the sniffer valves 27a and 27b described above. have.

Next, with reference to FIG. 1 and FIG. 2 again, the container mounting base 40a (40b) and the other up-down movement mechanism are demonstrated.

In FIG. 2, reference numeral 50 denotes a rotor that rotates together with the above-mentioned filling liquid storage tank 1 around the shaft center 0, and 51 denotes a cylinder which supports the rotor 50 up and down, Reference numeral 52 is a guide rod inserted in the cylinder 51, the guide rod 52 is fixed to a part of the rotor 50, the side of the supply of compressed air from the air hose 53 A receiving air passage 54 is laid.

A pair of guide cylinders 55a and 55b are provided on the upper portion of the cylinder 51, and the sliding cylinders 57a having the upper surfaces of the container holders 40a and 40b on the guide cylinders 55a and 55b. ) 57b is fitted.

(58a) (58b) is a guide cylinder for holding a bottom fitted inside the sliding cylinders (57a) (57b), which is fixed to the cylinder (51), and has a guide cylinder (58a) for holding the bottom ( 58b) and the inside of the cylinder 51 are communicated with the passage 59a, 59b.

Therefore, the sliding cylinders 57a and 57b are subjected to upward force by the compressed air supplied to the cylinder 51, and the rising limit thereof is the rods 60a and 60b fixed to the sliding cylinders 57a and 57b. The stoppers 61a and 61b at the lower end are limited in positions abutting the guide portions 68a and 68b holding the bottom.

Moreover, the roller 64 is supported by the lower end part of this cylinder 51, and this roller 64 is engaged with the cam surface 65 formed in the main surface of the lower end part of a cylindrical body.

Since the cylinder 51 is pushed upward by the pressure of the compressed air supplied therein, it moves up and down in accordance with the shape of the cam surface 65 with rotational movement.

In addition, the roller mounting table 40b constituting one of the outer container mounting rows B is provided with a roller 66 supported on a shaft in the horizontal direction at the lower end of the rod 60b. Is engaged with the cam 68 provided in the stationary frame 67.

The cam 63 is installed in correspondence with the above water plate 105. When the container mounting base 40b reaches the position of the water plate 105, the cam 63 engages with the roller 66 to force as shown in FIG. The rod 60b, the sliding cylinder 57b, and the container base 40b are lowered, and the interference between the container base 40b and the storage guide plate 105 is prevented.

With the above configuration, the device is supplied with the same shape as the container when the container is supplied on the container holders 40a and 40b with the rotation of the filling liquid reservoir 1 and the rotary frame 50. ), And the mounting table moves up and down at once in response to the up and down movement 51 of the cylinder accompanying this movement.

That is, the cylinder 51 is pressed upward by the compressed air supplied therein, and since the rising position is regulated by the cam surface 65, when the height of the cam surface 65 at the filling position into the container rises, With the cam surface, it rises toward the filling nozzle not shown, and the mounting base 40a, 40b and the container 18a, 18b are raised.

Then, the container guide mechanisms 17a and 17b pushed by the containers 18a and 18b are lifted up, respectively, so that the rollers 13a and 13b of the respective mechanisms 17a and 17b are arm 16a and 16b, respectively. It becomes the position which can interfere with.

And each roller 13a (13b) is rotated and conveyed according to the rotation of the tank 1, and each roller 13a (13b) interferes with the arm 16a (16b), and this is the direction of a 3rd degree arrow (a). When rotated, each of the interference arms 22a and 22b is rotated in the direction of the third arrow B as described above to interfere with the cams 6 and 10, respectively. Is rotated in the direction of the arrow c of FIG. 3 by the respective interference arms 22a and 22b, and the rotation of each cam 6 and 10 is forked through the rotation shafts 3 and 7. 4) (9) to open each valve of the internal and external gas injection filling nozzle.

This is a pressurized gas as known in the art. In general, inert gas is filled in the container, and then filling of a filling liquid such as a chemical liquid is performed, and when the work is completed, each cam 6, 10 abuts on a fixed cam not shown in the drawing, and the arrow 3c of FIG. Each valve is closed by turning in the opposite direction.

When the gas is injected, one of the pair of container mounting bases 40a and 40b, for example, when the container 18a of the container mounting base 40a is not supplied due to some cause, the other container 18b. The filling operation is carried out in the same manner as described above on the supplied side. On the side where the vessel 18a is not supplied, the vessel guide mechanism 17a does not rise even when the vessel mounting base 40a rises. Therefore, the roller 13a and the arm 16a do not interfere.

As a result, the interfering arm 22a that can interfere with the cam 6 remains in a non-interfering position that cannot interfere with the cam 6, so that the cam 6 passes through the interfering arm 22a while being in the closed position. The filling operation is not performed.

In other words, to achieve no filling without a bottle. In addition, even if an unexpected force is applied to one of the mounting bases due to different dimensions in the height direction of the container clamped between the pair of container mounting units 40a and 40b and the container guide mechanisms 17a and 17b. The stands 40a and 40b are elastically supported by the cylinder 11 by the pressure of the compressed air, and the mounting table to which the force is applied is elastically displaced downward and absorbs them. It can prevent it in advance and can fill a container. Next, when filling of the filling liquid is completed, the cam 29 of the sniffer mechanism is rotated in contact with a fixed cam (not shown) fixed at a required position by the rotation of the tank 1.

Then, the snift shaft 28 is displaced in the leftward direction of the fifth degree by resisting the spring 37 by the cam surface 29a of the cam 29, whereby the cam portion 28a of the snift shaft 28 ( The sniffer valves 27a and 27b engaged with 28b are also displaced against the springs 35a and 25b to open the sniffer holes.

As a result, as described above, the remaining space in the upper portion of the vessels 18a and 18b and the pressurized gas enclosed in the passages 25a and 25b are restricted by the orifice passages 30a and 30b. Upon receipt, the gas is gradually discharged into the atmosphere, and the pressure in the vessels 18a and 18b gradually decreases to atmospheric pressure.

When the pressure in the vessels 18a and 18b approaches or reaches atmospheric pressure, the vessels 18a and 18b are dropped by the vessel holders 40a and 40b and discharged out of the charger, while the cam 29 The fixed cam (not shown) returns to the original position, whereby the sniffer shaft 28 and the shunt valves 27a and 27b also return to their original positions, thereby closing the sniffer hole.

In addition, in the above embodiment, the swift shaft 28 is moved back and forth by the rotation of the cam 29. However, the cam 29 is omitted. The snift shaft 28 can be moved back and forth. In addition, as shown in FIG. 7 and FIG. 8, the sniffer shaft 28 is rotatably held in the ordinary member 32, and the cam 29 is fixed to the snift shaft. In the 28, a pair of cam portions 28a and 28b having a cam surface formed in the circumferential direction is formed so that the above-described opening / closing operation of the sniffer valves 27a and 27b is caused by rotation of the sniffer shaft 28. You can also control it.

As for the valve opening / closing mechanism, as shown in FIG. 9, each of the filling nozzles 23a (see Fig. 9) is the same as the above-described charger, which is provided with the pair of filling nozzles 23a and 23b in the tank 1, respectively. 23b) may be controlled independently depending on the presence or absence of the container.

In the above-described embodiment, the position control of the interference arms 22a and 22b in accordance with the presence or absence of the containers 18a and 18b is performed by a mechanical mechanism. Others, for example, the interference arms 22a and 22b Or the interference member is connected to a solenoid, and electrical control of each solenoid detects the presence of a limit switch operated by the rollers 13a and 13b, or directly in the presence of the vessels 18a and 18b. You may carry out as a photoelectric tube.

In addition, in the configuration of the container holders 40a and 40b, springs may be used instead of or in combination with compressed air for their elastic support, but according to the configuration as shown in the drawing, the structure may be simplified. There is this.

Similarly, a spring may be used for rolling up the cylinder 41 which is the lifting body, and a cam having a raceway groove may be used to impart a positive upward and downward motion to the lifting body.

In addition, in the drawing display example, the conveyance plate 105 is provided in order to facilitate the conveyance of the container between the inner container placing rows A, and for this reason, the outer container placing table 40b is conveyed to the conveying plate 105. Although the guide mechanism which lowers by the part is provided, this mechanism is not necessarily required, For example, what is necessary is just to provide the outer container mounting base 40b lower than the inner container mounting base 40a beforehand.

In addition, if the pair of mounting tables are formed in a shape of contact with each other, the container is slid over the outer mounting table, and then the feeding plate 105 is supplied to the inner mounting table. It becomes unnecessary.
